Accessgin facts hash from manifests

[Arnau]

Hi all,

I'm having the first experiences with puppet 5 & facter 3 

In old puppet versions I tend to add debug messages like:

notify { "OS : {::osfamily}: }

and it usually worked.

According to https://puppet.com/docs/puppet/5.3/lang_facts_and_builtin_vars.html#accessing-facts-from-puppet-code I can still access the facts using the old way, but it recommend to use the facts has, so the new code should look like:

  notify { "OS: $facts[os][family]": }

But when I do that I get the full list of facts and [os][family] at the bottom:

Notice: OS: {agent_specified_environment => test, aio_agent_version => 5.5.1, architecture => x86_64, augeas => {version => 1.10.1}

[.... TONS OF FACTS ...]  clientversion => 5.5.1, clientnoop => false}['os]['family']"

If I use the same syntax in a conditiona statement:

  if $facts['os']['family'] == 'RedHat' {

    notify { "I'm a RedHat": }

  }

then it works:

Notice: /Stage[main]/Common::Yumrepos/Notify[I'm a RedHat]/message: defined 'message' as 'I\'m a RedHat'

So, what's wrong with the above notify? 

TIA,

Arnau

first notify, the index should be quoted ....

notify { "OS: $facts['os']['family']": }

That us unfortunately wrong - it will produce the entire $facts hash as
a string followed by the *text* "['os']['family']".

The correct way is to write:

notify { "OS: ${facts['os']['family']}": }

Or, if you like:

notify { "OS: ${facts.dig('os', 'family')}

(or by using the "pick()" function from stdlib which is similar to "dig()")

Hi,

first of all, thanks for your answer.

Using your code I still see the whole $facts hash....

notify { "OS: $facts['os']['family']": }

As Henrik mentioned it must be:

notify { "OS: ${facts['os']['family']}": }

Best,

Arnau
